With a staggering net worth of $47 billion as of 2024, Mars holds a prominent position among the richest women on the planet. As one of the heirs to the Mars family fortune, she has played a vital role in the growth of the company, which is best known for producing iconic products like M&M’s, Snickers, and Pedigree pet foods.

However, Jacqueline Mars is more than just an heiress to a candy empire. She has built her fortune through her involvement in the family business and her astute management of wealth, while also dedicating significant efforts to philanthropy and environmental conservation.
The Mars Family Legacy
Mars, Incorporated was founded in 1911 by Jacqueline’s grandfather, Frank C. Mars, in Tacoma, Washington. The company started as a small candy business, with the first product being a variety of buttercream candy. However, it was the introduction of the Milky Way bar in 1923 that set the company on the path to becoming a global confectionery giant. Frank’s son, Forrest Mars Sr., who was Jacqueline’s father, joined the company and expanded its reach significantly by introducing new products and implementing innovative business strategies.
Forrest Mars Sr. was instrumental in making Mars, Incorporated one of the largest and most successful privately-held companies in the world. His forward-thinking approach led to the development of iconic products such as M&M’s and the acquisition of pet food brands like Pedigree and Whiskas. His legacy was passed down to his children, including Jacqueline, who inherited a share of the family fortune.
